Prior to 2010, K17FA relayed an over-the-air signal of the cable channel TV Land, making it the only broadcast affiliate of the network.

The network reaches 15.7 million television households throughout the United States through a variety of sources, including broadcast affiliates, cable, and over internet television on the SkyAngel platform.

The company plans to license the technology to NBC's broadcast affiliates and others that want to create a multimedia presence on the Internet.

MTV2 aired on channel 56 for about a year and a half but ended in 2002 as MTV2 dropped broadcast affiliates after contracts expired.

At first, it was the sole broadcast affiliate of TechTV, allocating 20 hours per day to the network with four daily hours of local programs.

Local broadcast affiliates used to be the farm teams where networks could groom younger talent.

Oregon State also has an extensive network of broadcast affiliates.

Abroad, CNN has 18 bureaus, 37 correspondents and anchors and more than 190 contributing broadcast affiliates.

It began being shown Wednesday on national cable and on broadcast affiliates in Nevada, New Mexico, Ohio, Pennsylvania and West Virginia at a cost of $1.3 million.

By the end of next month, it plans to use its available channels to offer the four major local broadcast affiliates to each of 20 to 25 markets, or about half of the nation's TV households.
